Rationalizing selection of ring-radial type structure for telecommunications network.

The comparative analysis of radial and ring-type structures with an equal number of communications centers is generally performed during the system design and construction of primary cable communications networks and telecommunications networks. This article presents the refined mathematical expressions determining the geometric and harmonic average relative efficiency coefficients for the rationalizing of the ring-radial type structure selection for the construction of public telecommunications networks. The obtained network efficiency index dependencies presented in this article can be used in the construction of telecommunications networks. [ABSTRACT FROM AUTHOR]
